- is guided, arepositively moved by the gear of the cinematograph. While in the prior arrangements of this kind the customary guiding of the endless film over individual rollers disposed in diagonal rows is dispensed with, the present invention has for object to render possible the positive drive of film guiding rollers also in such case, where the rollers are disposed in the customary manner in diagonal rows, I which has proved most suitable for local reasons and the run of the film. For this purpose the present invention consists in that the rollers of one diagonal row are in operative connection by means of a chain or rope, driven by'the gear of the cinematograph.

One mode of construction according to the invention is illustrated in the drawing.

Here the film b traveling through the cinematographic apparatus a is guided in the usual manner over a' number of rollers 0 disposed in diagonal rows. the one diagoiial row (left top corner of the drawing) are coupled by means of a chaln d The rollers of or any other suitable ulling member in such a way, that the chaln is led over chain- 4 wheels, which latter are provided on the axles of said rollers.

The lowermost of the axles of the guiding rollers in the diagonal row to be set in'operatlon receives its motion through the gear of the cinematograph a by means of a chain 9.

Claims:

1. In cinematograph apparatus, the combination with the film, and the guiding rollers for the film arranged in rows diagonally disposed with respect to the projection apparatus, of means in connection with one of 5 the rows of rollers for coupling said rollers together and driven by the operating means for the apparatus.

2. In cinematograph apparatus, the combination with the film, and the guiding roll- 60 ers for the film arranged'in rows diagonally disposed with respect to the projection ap-' paratus, of means in connection with one of the rows of rollers for coupling said rollers together and driven by the operating means 65.
